Answer:
20
Step-by-step explanation:
nPr = n!/(n-r)!
5P2 = 5!/(5-2)!
= 5!/3!
= 5×4×3!/3!
= 5×4
= 20
A factor of 14 is 7, and it isnt a multiple of 2.
7 x 2 = 14
Answer:
find the average.
Step-by-step explanation:
Answer:
<em>In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables). The case of one explanatory variable is called simple linear regression. For more than one explanatory variable, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable.</em>
Answer: Not proportional
Step-by-step explanation:
Ratio of pages read by Jim on Tuesday to minutes =![\frac{24}{40}=\frac{3}{5}=3:5](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B40%7D%3D%5Cfrac%7B3%7D%7B5%7D%3D3%3A5)
Ratio of pages read by Jim on Wednesday to minutes =![\frac{18}{24}=\frac{3}{4}=3:4](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B24%7D%3D%5Cfrac%7B3%7D%7B4%7D%3D3%3A4)
But ![\frac{3}{5}\neq \frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%5Cneq%20%5Cfrac%7B3%7D%7B4%7D)
Therefore, the ratios of pages read to minutes on Tuesday and Wednesday are not proportional.
